timestamper - prefix lines with the timestamps of their arrivals.


version 0.2.1


    $ long-running-process | timestamper | tee mylog.txt


App::Timestamper is a pure-Perl command line program that filters the input so the timestamps (in seconds+fractions since the UNIX epoch) are prefixed to the lines based on the time of the arrival.

So if the input was something like:

    First Line
    Second Line
    Third Line

It will become something like:

    1435254285.978485482\tFirst Line
    1435254302.569615087\tSecond Line
    1435254319.809459781\tThird Line
